Effect of local triamcinolone acetonide (TA) injection on mechanical pain behavior induced by spinal nerve ligation (SNL). Baseline withdrawal threshold to mechanical stimulation of the hind paws was measured in the ipsilateral paw on three measurements taken over 5 days before the surgery, and the average is plotted as the postoperative day 0 value. *, Days on which there was a significant difference between group SNL+TA and group SNL rats (one-way ANOVA). The ipsilateral reduction in threshold caused by SNL alone was significantly different from the normal group on all postoperative days; for clarity no symbols are added to indicate this.
